WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 405,282, dated June 18,1889.

Application filed March 14, 1889. Serial No. 303,300. (Model) To allwhom it may concern.-

Be it known that I, AUSTIN F. TEIGEN, a citizen of the United States,residing at atson, in the county of Chippewa and State of Minnesota,have invented new and useful Improvements in Vashing-Machines, of whichthe following is a specification.

The invention relates to improvements in' washing-machines; and itconsists in a certain novel construction and combination of devicesfully described hereinafter in connection with the accompanyingdrawings, and specifically pointed out in the claims.

In the drawings, Figure 1 is a perspective View, partly broken away, ofa washing-machine embodying my improvements. Fig. 2 is a side View,partly in section, showing the opposite end. Fig. 3 is a plan View. Fig.4 is a sectional view on the line x :0 of Fig. 3. Fig. 5 is alongitudinal sectional view of one of the cylinders. Fig. 6 is a detailsectional View of a portion of the main driving-shaft.

Referring by letter to the drawings, the suds-box A may be of anydesired shape, (the rectangular shape shown in the drawings beingpreferred,) and inwardly-inclined supporting-arms B B are arranged on aninclined platform C, at one side of the box, and project over the centerof the box.

A horizontal driving-shaft D is journaled in bearings d (Z, providednear the lower ends of each of the supporting-arms, and on one squaredend of the shaft is keyed a cam-roll E, having the zigzag or irregularcam-groove e formed in its periphery. On the other squared end of thedriving-shaft is fitted a small sprocket-wheel F, having a pinion Fsecured rigidly to its inner side or formed integral therewith, and thesprocket-wheel is provided on its outer side with a collar f, whichembraces the driving-shaft and carries a set-screw f, whereby thesprocket-wheel may be clamped firmly in place on the shaft. The squaredend of the shaft projects beyond the end of the collar f and a tubularcrankshaft G, which is journaled in a bearing in the end of the suds-boxand has a square bore g, which fits on the driving-shaft, therebyenabling the latter to be rotated by turn ing the crank G. Thecrank-shaft preferably extends through a suitable packing-box g, toprevent the contents of the suds-box from escaping at that point.

A swinging frame H is arranged adjacent to the supporting-arm B B, andit consists of arms h h, similar to the arms B, mounted at their lowerends on the driving-shaft, (or otherwise pivoted to the saidsupporting-arms,) and the cross-bar h, which connects the arms h h atintermediate points. A curved leafspring I bears against the center ofthe crossbar to press the upper ends of the swinging arms h toward thesupporting-arms.

Square shafts K K are mounted in bearings at the free ends of thesupporting and swinging arms, respectively, (the said shafts beingrounded where they fit in the bearings to enable them to turn,) and onthe shafts are fitted the washing-cylinders L L, which are shorter thanthe shafts, and are capable of a sliding movement thereon. Thewashing-cyl-.

inders consist of the heads or disks M M, having square centralapertures m m to fit the shafts K K, whereby the cylinders are caused torotate with the shafts, and the cylindrical jacket or shell m, which isroughened or provided with small kn obs or projections m to rub theclothes.

Sprocket-wheels N N are fitted on the projecting ends of the shafts K K,which are adjacent to the sprocket-wheel F, and said wheels are providedwith setscrews n n to impinge against the shafts, and smallsprocket-pinions N N are formed on the outer sides of the saidsprocket-wheels, for a purpose to be hereinafter explained.

A sprocket-Wheel 0, similar to the wheel F, is mounted on a stub-shaft 0at the lower end of one of the swinging arms h, and it is provided witha pinion O, which meshes with the pinion F, whereby, when thedrivingshaft is turned, both sprocket-wheels F and O are rotated.

Sprocket-chains P P connect the sprocketwheels N N to thesprocket-wheels F and 0, respectively, whereby the washing-cylinders arerotated in opposite directions or toward each other when the crank isturned to the right, as shown by the arrows in the drawings, and as thesprocket-wheels N N are larger than the Wheels F and O the cylinderswill turn slowly.

Operating-levers Q Q, are pivoted to brackets q q'on the supporting andswinging arms 13 77., adjacent to the cam-roll, and are .provided attheir lower ends with anti-friction rollers R R, which travel in thegroove of the cam-roll at diametrically-opposite points of the latter,whereby as the driving-shaft is rotated the levers are oscillated inopposite directions, the upper end of one lever swinging toward thewashing-cylinders, while the other swings away from the same.

The 'ashing-cylinders are provided at the ends which are adjacent to theupper ends of the levers Q Q with collars S S, having peripheral groovess s, and straps T T are fitted looselyin these grooves and are connectedto the free ends of the levers by the links U U. The links are connectedto the levers by the pivoted bolts a n, which engage perforations V inthe upper ends of the levers, a series of these perforations beingprovided in each lever to enable the throw of the cylinders to beadjusted at will.

From the above description it will be seen that the adjustable washingcylinder L (which is mounted on the swinging frame) may be drawn awayfrom the roller, as shown in dotted lines in Fig. i, and therefore asthe clothes or fabrics to be washed are fed be tween the cylinders aconstant pressure is exerted thereon, but the adjustable cylinderaccommodates itself to the thickness of the material.

lVhen the crank is turned, the washingcylinders are given two movementsarotary movement which draws the clothes slowly through, so as to exposeall parts thereof to the surfaces of the cylinders, and a longitudinaloscillating movement in opposite directions, which rubs and therebycleanses the clothes.

If it is desired to wring or compress the clothes to expel the water,the cylinders are disconnected from the upper ends of the levers byremoving the pins \V IV, which connect the links to the straps, and thesprocketehains are engaged with the sprocket-pinions N N above referredto. The cylinders'then revolve with the same rapidity as thedriving-shaft.

I have now described my improvements in washing-machiries with thepreferred means for carrying my object into effect; butI desire it to beunderstood thatI do not limit myself to the precise details ofconstruction as herein set forth, as various minor changes may be madetherein without departing from the spirit and intent of the invention.

Having thus described the invention,- I claim 1. In a washing-machine,the combination of the parallel squared shafts, the washingcylindersmounted on the shafts and adapted to slide longitudinally thereon andprovided with grooved collars S S, the driving-shaft geared to thesquared shafts and carrying a cam-roll having an irregular groove, thelevers provided at one end with anti-friction rollers traveling in thesaid groove, and the straps fitting on the grooved collars and connected by links to the free ends of the said levers, substantially asspecified.

2.In a washing-maehine, the combination of the cylinder L, provided witha shaft which is mounted on stationary supportingarms, the swingingframe carrying a cylinder L and actuated by a suitable spring to holdthe cylinders in contact, the driving-shaft geared to the said cylidersand carrying a cam-roll, and the levers connected to the cylinders andoperated by the cam-roll, substantially as specified.

3. In a washing-machine, the combination of the parallel squared shaftsprovided with sprocket-wheels N N, the cylinders mounted on the saidshafts and capable of a sliding movement thereon, the driving-shaft provided with a sprocket-wheel F, the sprocketwheel 0, geared to thesprocket-wheel F, the sprocket-chains connecting the wheels F O to thewheels N N, and the levers connected to the cylinders and operated by acam-roll on the driving-shaft, substantially as specified.

l. In a washing-machine, the combination of the parallel revolubleshafts carrying washing-cylinders and provided with sprocketwheels N N,the squared driving-shaft, the sprocket-wheels F 0, connected to thedriving-shaft and geared to the sprocket-wheels N N by thesprocket-chains P P, and the crank-shaft provided with a square bore tofit on the driving-shaft, substantially as and for the purposespecified.

5. In a washing-machine, the combination, with the suds-box, of theinclined supportingarms B B, the shaft mounted in bearings at the outerends of the supporting-anus and carrying a washing-cylinder L, thedrivingshaft mounted in bearings near the lower ends of thesupporting-arms and geared to the cylinder L, the swinging frame pivotedon the driving-shaft and carrying awashingcylinder L, which is geared tothe drivingshaft, and the crankshaft mounted in a bearing in the side ofthe suds-box, passing through a packing-box therein and provided with asquared bore to fit on the squared end of the driving-shaft,substantially as specified.

6. In a washing-machine, the combination of the parallel squared shaftscarrying washing-cylinders and provided with sprocketwheels N N, havingsprocket-pinions N N, the driving-shaft carrying a cam-roll and providedwith sprocket wheels I?
